Abstract
The instant invention relates to a spinning process and to a device for the production of a yarn. In the spinning process the fibers are conveyed to a perforated collection surface which is subjected to suction in one zone. They are brought together into a fiber accumulation on the collection surface. The fiber accumulation is drawn off from the collection surface and twisted into a yarn of predetermined twist in a twisting element which follows the collection surface in the direction of yarn draw-off. The fibers are accumulated at a suction edge constituting a collection line and are pre-twisted at said collection line.
